So what I've wanted to buy myself a long time, now, just before Christmas, I finally did it. The ceiling is 1 x 1 meter, in a plastic sleeve, has an eye for hanging, so that the ceiling is always at hand. In addition, two black straps hang out, where you can pull in an emergency to bring out the ceiling and open. (Unpacked I have now is not.) I will place them in the kitchen next to the stove. So it is faster than any fire extinguisher at hand. How fast can hot fat catch fire. One should really have something like that at home!
